Zinc die casting parts at Sinbo Precision offer exceptional dimensional accuracy and surface finish through hot chamber die casting technology. Our zinc casting process injects molten zinc alloy into precision steel molds under high pressure, producing parts with tight tolerances, excellent surface quality, and complex geometries that are ideal for precision applications. Zinc's low melting point and excellent fluidity enable the production of thin-walled parts with intricate details and fine features.
Our zinc alloy portfolio includes Zamak 3 for general purpose applications with excellent castability and mechanical properties, Zamak 5 for enhanced strength and hardness, ZA-8 for improved creep resistance, and ZA-12 for high strength applications. Each alloy formulation is optimized for specific properties including tensile strength, hardness, impact resistance, and corrosion resistance. Our experienced team provides expert guidance on alloy selection to ensure your zinc die cast parts meet your exact requirements.
Every zinc die cast part undergoes meticulous quality control including dimensional inspection, visual examination, and mechanical testing when required. We offer comprehensive secondary operations including CNC machining, surface finishing, plating, and assembly to provide complete, ready-to-use components. With our China factory and efficient logistics, you can receive your zinc die cast parts quickly, ready for immediate use in your products. Our engineering team provides design for die casting guidance to optimize your parts for manufacturability and cost efficiency.

Our minimum order quantity is 500 pieces for production runs. For prototype quantities, we can accommodate smaller orders with appropriate tooling costs. Economical production typically begins at 5000 pieces or more.
Tooling lead time is typically 2-3 weeks depending on mold complexity. Production lead time is 1 week after tooling is complete. Expedited options are available for urgent requirements.
We accept STEP, IGES, Parasolid, and native CAD files. Our engineering team can work with various formats and provide design for die casting guidance to optimize your parts for manufacturability.
We offer comprehensive post-processing including CNC machining for tight tolerances, shot blasting for surface preparation, plating (chrome, nickel, zinc), powder coating, and assembly services for complete components.
Zinc die casting offers excellent dimensional accuracy, smooth surface finish, high strength-to-weight ratio, good corrosion resistance, excellent electrical conductivity, and the ability to produce thin-walled parts with complex geometries. Zinc's low melting point also enables faster cycle times and longer tool life.
Yes, zinc die cast parts can be plated with various finishes including chrome, nickel, copper, and zinc plating. Plating enhances corrosion resistance, improves appearance, and provides additional surface properties for specific applications.
